11 Claims. (Cl. 9H2) our invention relates to an improvement in an apparatus for continuously wrapping ice cream or other products and its novelty consists in the means for carrying out the same.

It is a division of our application No. 750,432 filed Oct. 29, 1934 which has matured into Patent No. 2,014,961, September 17, 1935 and is divided out and filed as a separate application in accordance with the requirement of the Patent 11o Oiflce in said application.

There is now on the market a paper tube form ing and filling machine for wrapping ice cre 1:: or other products continuously, known as the Clarence W. Vogt machine and made under to United States Patents Nos. 1,801,740, 1,801,863,

1,801,884 and 1,906,183 but it uses glue in securing the wrapper together. This is objectionable because it is unhygienic because the glue con tsminates the material in the container and also because it either does not stay fastened with sufficient security it inadequately glued or is too difiicult to remove if glued too much.

Our apparatus solves these problems and furnishes a new wrapper or container which is positiveiy locked or fastened together so that the fastoning is very strong against inside pressure but fragile when pulled apart on the outside as is desired in unwrapping the container.

Referring to the'drawings Figure l is a top plan 30 view of our mechanism as it is attached in position' on said patented Vogt paper tube forming and filling machine.

1n the drawings e is a hygienic ice cream or other material filling tube of said vogt paper tube forming and filling machine rigidly mounted in a fixed position by means of the clamping bracket o l of usual construction, which is rigidly secured at t to a door or base 9 in the usual well known manner. An inner forming tube 10, also held rigidly in position by brackets 1,,is mounted over said hygienic tube 6 with a. very slight insulating as space of air between. A lower or bottom shoe ll constituting the outer lower half oflan outer forming tube is held rigidly in a. fixed position by means of supporting brackets i2 secured in the usual well known manner at is to the base or -floor 9 so that it is immediately around the lower 5 half of the inner forming tube it. An upper shoe It completing the outer forming tube with the lower shoe H is mounted thereon by means of arms 15 which terminate in plates it at one end which are rigidly secured at ii to the said upper 10 shoe it and are pivoted by means of the usual bearings on shafts it in the heads of brackets is rigidly secured at it in the well known manner to the plate or floor 9. These arms is are counter balanced by adiustable weights 2i mounted thereon in the usual well known manner with set screws 22, so that said upper shoe it can be raised and lowered quickly-and easily. The upper shoe i t also has slotted ears tt-which are in alignment with similar ears 2t integral with the lower shoe ii and which carry clamping bolt members with a spring member 26 under the cars it on said bolt so as to permit of an easy riding of said upper shoe it on said lower shoe it as the paper tube being formed passes therethrough. 25

A pair of circular plates 2i having puncturing or piercing teeth 28 arranged around the entire outer periphery of said circular plates are mounted on shafts 29 so as to rotate freely thereon, and

said shafts 2d are rigidly secured at 30 in the 30 usual well known manner to the arms 3i, which in turn are pivoted at 32 in the usual manner on the posts 33 so as to turn freely thereon,- and said arms ti have handles 84! extending from the outer ends thereof so that said toothed plates 21 can 35 be swung out of engagement as desired. There are also limiting elements 35 rigidly secured at 36 to the plate or floor 9 so as to prevent the toothed plates 21 from swinging beyond the desired point for eifectingthe piercing of the paper 40 tube and interlocking of the se. The teeth 28 have their highest point 31 in the rear portion of the tooth 28 as it rotates with the'tubular container being formed in our device and the high point tl runs down to a low point it at the front of the tooth it as it rotates.

There is a slot 39 cut through the upper shoe It at the right side of Figure 4 as shown in the drawings, and a narrow shearing slot3t on the side of the inner forming tube it for the teeth 28 of the plate 21, and a slot 40 on theleft hand side of Figure 4 through the lower shoe ii and a narrow shearing slot 40 on the side of the inner forming tube ill for the clearance of the teeth 28 on the plate 21 on that side.

A roll of paper 5| mounted on shaft 52 in brackets 88 mounted on frame 60 which supports the base or floor 9 is. adapted to continuously supply the under strip of paper 42 around idler roller 51 and under idler roller 58 mounted in the usual way on shafts 59 in sub-frame member 6|, and a second roll of paper 54 mounted on shaft 55 in brackets 56 also supported on the frame 60 is adapted to continuously supply the upper strip of paper 4| to our mechanism over idler roller 62 and under idler roller 63 supported on shafts 04 mounted in the usual manner in said sub-frame 8|.

The paper pulling, mechanism is shown at-the right hand end of Figure 6 and has a driving gear 65, broken away for convenience in illustration,.mounted in the usual way on the driven shaft 86 being connected to a source of power not shown. Said driving gear 85 meshes with driven gear 81 rigidly mounted on the shaft 88 in the usual well known manner, which in turn is supported in the sub-frame l0 and a second driven gear 68 rigidly mounted in the usual manner on shaft supported in said sub-frame III is in mesh with driven gear 61 whereby driving gear 85 travels clockwise and driven gear 81 in mesh therewith travels counter clockwise, and driven gear 69 in mesh with driven gear 61 travels clockwise. A sprocket 12 also rigidly mounted on said shaft 68 travels therewith and a chain -13, which for convenience in drawing is shown broken at both ends, travels over said sprocket l2 and also over sprocket 14 mounted on shaft 15 which is supported in said sub-frame 10 in the usual well known manner so as to rotate freely therein. A sprocket I8 is also rigidly secured to shaft H and a second chain 11, which is also shown broken for convenience in illustration, travels over said sprocket 16 at one end and over a second sprocket I8 at the other end,

which sprocket I8 is mounted on shaft IS in turn mounted in the well known manner in said subframe '10 so as to rotate freely therein. The chains I3 and 11 are composed of links 80 each of which has a flange or pressing member 8| secured thereto which have gripping lips 84 at each side and semi-circular cut out portions 82 in the middle sectionsadapted to fit over and not contact with the continuously formed cylindrical container. These upper and lower flange or gripping members 8| as they come tightly together at 83 as to, their outer edges or lips 84 will grasp by said pairs of aligned lips 84 in Figure 6 the flange 45 and as to the other pair of lips 84 on the far side of Figure 6 grasp the flange 46 so as to pull and feed along the said continuously formed cylindrical container.

In operating our device as described in conjunction with the Vogt paper tube forming and filling machine, a strip of paper will be run from the usual reel holding the same (as shown in Fig. 6) over the inner forming tube i0 and the shoe M will be raised by means of the pivoted arms l5 so that said upper strip of paper 4| may be placed in position over said inner forming tube In and the shoe M will then be lowered into position thereover, and an under strip of paper 42 will be drawn through over the under side of the inner forming tube i0 and under the lower outer shoe II, and as there are slots 43 and 44 the under strip of paper 42 will project through said continuous slot 43 to form a flange 45, and the upper strip of paper 4| will pass through the continuous slot 44 forming an outer flange 46. It will also be apparent that the upper strip of paper tube for holding the ice cream or other product to be filled thereinto.

The two strips of paper 4| and 42 are gripped by the usual Vogt conveyor (see Figure 6) and pulled through the mechanism described in an absolute synchronism, thereby forming the continuous tubular paper tube or container for filling.

Our device locks and securely fastens together 15 these two formed semi-tubular members 4| and 42 by means of the teeth 28 of the plates 21 which rotating in the same direction with the line of travel of said paper impinge upon said paperand pressing the same against the shear- 20 ing edges of the slots 39 and 40' form a continuous series of punches or piercings through eachside of the said overlapped portions 41 and 48 of the semi-tubular paper members 4| and 42, whereby the series of paper tabs 49 are pro- 25' jected inwardly and backwardly of the line of movement. These inwardly projected tabs 49 are flattened down as the tube is drawn on over the inner forming tube I0.

As the tube thus formed and secured together 30 is filled with ice cream at a point beyond the Figure 1 shown herein where the hygienic tube 8 ends within said paper tube. the ice cream or other product will fill said paper tube, and as the inwardly turned tabs 49 have been somewhat flattened down theywill be further flattened down and the slight openings filled by ice cream or other product being fllled into said paper tube.

As the continuous tubular container formed thus by the interlocking tabs 49 in the overlapping side edge portions of paper strips 4| and 42 is filled by ice cream or some other product, it is drawn onto a point where it is cut off in desired lengths and carried forward for further treatment as may be desired.

It will be particularly noted that the entirel novel container as shown in Figure 3 resulting from our process and apparatus has a continuous row of tabs 49 on each side projecting inwardly slightly and which, as the container is put under presure from the inside, causes said interlocked tabs to merely pull sidewise, causing a binding of the projecting tabs on the sides of the double hole in the two strips 4| and 42, and that the strength of this interlocking in that direction is more than could be overcome by any intended use of said container for ice cream or other product.

However, if the two flanges 45 and 48 are taken between the fingers of each hand and pulled 'gently, the tabs 49 are easily and without resistance lifted up and out of the holes made by piercing strips 4| and 42 because of the-direction of the pull or tension. Thus the novel container 50 formed by our apparatus completely solves the problem of a hygienic container having more than the recognized strength for holding the ice creanr or'oth'er product perfectly for shipment and handling'but being subject to quick and easy opening for use.

It will be apparent that a metal adaptable to the piercing and bending out of tabs may be used in our apparatus instead of a paper-like material and that many variations may be made in our invention without departing from the spirit and intent of the same.
